A polishing investigation revealed that all surfaces of rutile may have equal amounts of material removed for equal polishing times. Polishing for three minutes or less on the (110) surface produced polish pits which are correlated with surface dislocations introduced during fabrication. Etching of the (110) surface showed that for pits to form on this surface, the acid must boil. Experimental work and analysis was employed to determine the active slip systems and the effect of various surface and heat treatments on the yielding criteria and strain hardening of rutile. It is shown that both the {110} [001] and {101} <101> systems are extremely active, while the {112} <111> and {100} [001] systems are inactive in the orientations investigated. Polishing an "as cut" sample removed surface sources while quenching and abraiding introduced new dislocations.
